* Question
| What are the main research directions of some high-power tunable blue-green lasers? |
* Answer
| (1) Using a Nd:YVO4 laser with a working wavelength of 1342 nm, a green laser tunable from 503 nm to 505 nm can be produced by mixing the frequency of the pump and laser radiation in the KTP crystal cavity.When using a titanium-doped gems laser as the pump source, the adjustable range of the laser can be increased to 22 nm.
(3) Using the internal second harmonic to generate a resonance near the single-resonance optical parametric oscillator and the 5 mm BiB3O6 crystal from the green pump, continuous wave and magnesium doped stoichiometric lithium niobate as nonlinear materialsInfrared signal can realize a 450 mW continuous wave single-frequency blue laser. |
